The aim of the present study was to determine seroprevalence of Toxoplasma gondii infectionin stray cats and correlation with oocyst shedding and IFN-γ concentration. From April to August 2016, one hundred fifty-nine stray cats were captured from various localities in Mashhad area. The blood and fecal samples were collected from each cat. The serum samples were examined to detect antib...

Total IgM, IgA, and IgM-rheumatoid factor (RF) and IgA-RF were quantitated in the serum and synovial fluid of 35 seropositive and 8 seronegative rheumatoid arthritis (RA) patients, using a sensitive enzyme-linked immunosorbent assay (ELISA). Mononuclear cells isolated from peripheral blood and synovial fluid of three seropositive patients were also stimulated in vitro with phorbol myristat...

In response to the continuing debate whether seronegative and seropositive rheumatoid arthritis (RA) are parts of the same disease spectrum or are distinct disorders, we performed a comparative analysis of some laboratory characteristics. The test group consisted of 125 seronegative RA(93 female, 32 male), with titers lower than 1/64 as defined by Rose-Waaler test. The control group consisted o...

Pathogenesis in aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive neuromyelitis optica spectrum disorders (herein called NMO) involves complement-dependent cytotoxicity initiated by AQP4-IgG binding to astrocyte AQP4. We recently reported that rats lacking complement inhibitor protein CD59 were highly susceptible to development of NMO pathology in brain and spinal cord following direct AQP4-...

The ferrihydrite-goethite transformation in samples of pureand Mn-ferrihydrite was investigated in order to elucidate the effect of Mn(II) in the aging process. Samples of pureand Mn-ferrihydrites were aged for different times, and their structural changes were described on the basis of Rietveld structure refinements. A comparison of two series of samples with (A-series) and without Mn (F-serie...

The lipid pattern of blood serum has been studied in 32 patients with multiple sclerosis, in whom the disease was either remittent or slowly progressive. Although total lipids, free and esterified cholesterol, aand 0-lipoproteins and chylomicrons were found to be normal in patients, minimal and maximal values showed wider ranges than in controls. Cholesterol esters were slightly reduced (71,6 ±...

Serum samples of 749 sheep from 75 sheep flocks in Norway, i.e. 361 lambs (6 to 7 months old) and 388 adults (> 1.5 year), were analysed for antibodies to Ehrlichia equi. Ten animals from each flock were examined. Seropositive animals were found along the coast of southern Norway from Vestfold to Sør-Trøndelag (as far north as 63 degrees 38'N). Seropositive sheep were not found in southeast, ea...
